Advanced `All-In-One' Modem Chip From TDK Semiconductor Supports Caller ID, Blacklisting, Parallel Phone Detect.Business Editors and High-Tech Writers TUSTIN, Calif.--(BUSINESS WIRE)--Jan. 7, 2002 TDK TDK Türk Dil Kurumu (Turkish Language Council) TDK The Dark Knights (gaming clan) TDK Tokyo Denkikagaku Kogyo KK (TDK Electronics Co. Ltd. Semiconductor Corp., a leader in the design and manufacture of communications semiconductors for worldwide markets, has expanded significantly on its "all-in-one" 73M2901 introduced in 1999 with the release of the new 73M2901CL, a 3.3V single-chip modem that combines all the controller (DTE (Data Terminating Equipment) A communications device that is the source or destination of signals on a network. It is typically a terminal or computer. Contrast with DCE.  DTE - Data Terminal Equipment ) and data pump functions necessary to implement an intelligent V.22bis data modem. The 73M2901CL feature-rich set includes critical functions like Caller ID, blacklisting, parallel phone detect (Line-In-Use and Parallel-Pick-Up/Line-Seize), long space disconnect, inactivity timeout and programmable call progress. The 73M2901CL high performance, low power modem IC has integrated a great portion of the modem circuit on the chip, such as the microprocessor, DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive , analog front end, and hybrid driver. The 3.3V single chip architecture makes it physically small enough for the modular form factor, and virtually eliminates the need to specify hard-to-source passive components specific to other modem vendors. The device truly is a "one chip fits all" implementation for applications including set-top boxes, point-of-sale terminals, automatic teller machines, hand-held communication devices, metering devices, vending machines and smart card readers. Andy Mills, senior vice president for the company's Broadband Communications Products, said: "The 73M2901CL offers the highest level of integration available today. It lends itself to embedded applications by handling all of the data formatting, data pump control, call progress negotiation and call monitoring. "It offers a very simple serial interface, V.24, to the host over which commands and data packets are sent. The command style is an incredibly simple AT command set with enough user control to allow the embedded designer to customize the 73M2901CL for any application and any country in the world." The new 73M2901CL is based on TDK Semiconductor's implementation of the industry standard 8032 microcontroller core with a proprietary multiply and accumulate (MAC) coprocessor coprocessor Additional processor used in some personal computers to perform specialized tasks such as extensive arithmetic calculations or processing of graphical displays. , analog front end, Sigma Delta A/D A/D See advance-decline line (A/D). and D/A D/A See: Documents Against Acceptance . The ROM and RAM necessary to operate the modem are contained on the device. Additionally, the 73M2901CL provides an on-chip oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air and hybrid driver. The 73M2901CL high performance, low power modem IC is capable of data transmission and reception through 2400bps. Consuming as little as 9.5mA, the 73M2901CL is intended for embedded applications and battery operation. This device offers options for modem design from 2.7v to 3.6v with optional internal hybrid and country specific call progress support. TDK Semiconductor recently completed an instructional training CD ROM module demonstrating how the 73M2901CL, when used in conjunction with the company's protocol software, provides MNP/V.42/V.42bis data correction and compression protocols within a host platform. The self-paced multimedia CD ROM walks users through the general architecture, system requirements, software interfaces, and system integration methodology used to perform a successful integration of the software into a host-based system design. The protocol firmware integration CD ROM presentation is available upon written request. The 73M2901CL single chip modem is available in a 32-pin PLCC (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. , 32-pin TQFP See QFP. or a 44-pin LQFP See QFP. package. The devices are priced at $6.49 each in 10,000 unit quantities. Samples are currently available.
